HeavyPro | Rotaidem

What it does

HeavyPro reads your joystick and rudder pedals through SimConnect, the simulator's official interface. For every movement it calculates how the real aircraft would answer, from the aircraft type, its weight right now, how that weight is spread, airspeed and flight phase. Your stick then feels heavy, with the weight and momentum of a real airliner, instead of a light desktop stick that snaps instantly. It is not a fixed delay: the feel changes all the time with the aircraft, and full control travel is always there when you need it.

Feel presets. Normal, Medium and Realistic, or your own custom setting.
Automatic profiles. Detects the loaded aircraft and picks a matching profile.
Live tuning. Curve, expo, deadzone, sensitivity, rate limits and stick release, changed in flight.
Live aircraft data. Weight, balance, airspeed and flaps are read continuously, so a full 777 feels heavier than an empty one.
Airspeed aware. Response firms up as speed increases.
Safe by design. Pass-through when switched off, when the autopilot is on and while a flight loads.

What pilots say

See it in action

Leaves your aircraft alone

HeavyPro only changes the input you send. Everything else stays exactly as the developer made it.

No file changes. Aircraft, flight models and aerodynamic forces are never modified.
Your bindings stay yours. Only the axes HeavyPro has captured are changed. Anything bound another way is left untouched.
